Spring Frames, of. which the following is a specification.

This invention relates to a bed spring structure -an more particularly to a novel form of spring frame embodying certain improved spring securing means to ether with a convertible frame support where y the spring as a complete unitary structure becomes adapted for use with either Wooden or metal beds. 7

It has therefore as an object to provide a spring frame for beds which is-simple in construction and comprises effective means for" retaining the 'spring members properly seated with respect to the frame proper but which yet permits the full spring action to come into play at the desired time.

As a further object my invention provides a plurality of hangers or frame supports, which are slidingly mounted incertain novel adjuncts of the spring frame, whereby their operation is rendered exceedingly easy and the parts are few and arranged with an end to eliminate all ordinary chances of getting out of order, such as corroding and sticking'of small pivot pin bolts or the like: For the purpose of illustrating my inven ,tion, I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same has been found in ractice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which. my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described. It further consists of other novel features of construction, all as ill be hereinafter fully set forth. V

Figure 1 represents a vertical section of a portion of a bed spring embodying my in vention, showing the parts arranged for use in connection with .a metal bedstead; Fig. 2'

represents asimilar section showing the parts in position for use with a wooden bedstead; Fig. 3 represents a plan of a portion of the spring frame showing the supporting means applied to a metalybed; Fig. 4 represents a side elevation era portion of the spring frame; Fig. 5 represents a detail of construction showing the manner of securingthe guide bearing and the spring adjuncts.

Similar numerals of reference indicate corresponding parts.

Referring to the drawiugs. -In the drawings I have deemed it unnecessary to show a spring frame in its entirety as my invention can be readily understood by those skilled in the art from the parts shown and it will be obvious that the complete frame merely embodies a duplication of the parts here shown and described.

The spring frame proper,,in the present instance, comprises a plurality of longitudinally disposed metal cross bars 1 ,suitably spaced apart and preferably arranged with the width of each bar disposed vertically in order to form a strong rigid structure capable of resisting bending strains. Adjacent the ends the bars 1 are partially twisted and bent so as to form upstanding members 2, each series of which is connected together by a transverse bar 3 whereby a frame-work of light construct-ion isformed capable of withstanding hard usage and all stresses and strains to which the device may be subjected .in ordinary use. In addition to the end transverse bars 3, I providea plurality of tie rods twhichextend transversely of the frame, preferably in parallel relation.

increasing the strength of the structure very materially. It will of course be understood that these tie rods 4 are fixed at the ends to prevent displacement thereof as Well as to stance, is provided with a plurality of recesses 5 cut in the upper edge thereof and positioned in pairs, each pair being arranged adjacent a tie rod 4. These recesses 5 form seats for one of the convolutions of the helical springs 6. the arrangement being passing successively through the bars 1 and such that each spring is not only fixed as to longitudinal movement with respect to its bar 1, but is further held against transverse movement through engagement with a tie rod 4. Thus as shown in Figs. 4 and 5 the tie rod 4 is passed over one side of a spring convolution. then through the bar 1 and a ain, over the diametrically opposite side of the convolution, thereby effectively anchoring one end of the springs. The free ends of the respective springs 6 are secured in a similar manner to the latticed member 7 which may be of any desired or well known type for support ng the mattress or 7 like article.

8-designates a number of bearing strips interposed between certain bars 1 and in view of the fact that the construction of all are similaras well as their coiiperating adjuncts the description'will be confined to but one of these strips with its parts. The ends of the strip 8 are angularly disposed as,

"shown at 9 to abut the adjacent bars 1 where they are held by tie rod 4 in'fixed position, and in addition to which the fixed convolution of the adjacent spring 6 is po-- is utilized as a support for the said spring structure. In the present instance the end 1 1 is mounted for sliding movement in a slot or opening 15in the transverse bar 3 and has a depending liporflange 16 at its extremity which serves'the purpose of a hook to engage the side bar 17 of a metal bed and prevent thehanger' from becoming retracted or returned to its innermost position at the time it is intended to'be in operative' position.

In Fig. 1 I have shown the operative position of the hanger 13, the frame at this time being used in connection with a metal bed, While in Fig. 2 I have shown the hanger 13 pushed out of the way and inoperative, the frame then being supported directly on the slats ofa .wooden bed. The hangers 13 are-preferably made of malleable iron, but

of course I do not desire to be limited to any particular material, and it will be readily understood that any suitable material may be employed. The number of hangers 13 used may also be varied without departing from the scope of my invention as it is obvious that small frames will require a less number than large'ones and their position will accordingly be varied to suit the particular circumstances. In connection with the frame bars-1 attention is particularly' called to the recesses which form seats for the lowermost coil of each spring, in connection with which a crossed-tie rod is employed which is interwoven with the and there is little likelihood of such parts I becoming deranged, displaced or broken through careless manipulation of the hangers, or improper positioning thereof.

I am aware that it has heretofore been proposed in the patent to Sleeth, No.

1,070,298, and the patent to Trimble, No.

in such a manner that they may be readily operated by those unskilled. in mechanical movements and mechanism, and without undue manipulation of a multiplicity of parts,

My present invention is clearly differentiated from the devices of the foregoing patents, as will be apparent to those skilled in the art, since the hangers are mounted to slide in and out of my novel frame structure, and may readily be shifted from'one position toanother easily and quickly, and the use of rivets, bolts or similar means for pivoting the hangers are entirely dispensed with, thereby eliminating the corroding, rusting or sticking of the parts in use.

It will now be apparent that I have devised a'novel and usefulconst-ruction which embodies the features of advantage enumerated asv desirable in the statement of the invention and the above description, and while I have in the present instance shown and described the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be 'understoodthat the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim and desire .to protect by Letters Pat cut is j 1. In a device of the character stated, a spring frame comprising a plurality of cross bars spaced apart and suitably secured together, a suitable support yieldingly mounted on said cross bars, brace strips fixedly secured between certain pairs of'said cross bars, a hanger substantially of Z-shape slidingly mounted in each brace strip to engage a bed frame under certain conditions to support said frame, and means to prevent said. hangers from being detached.

'2. In adevice of the character stated, .a spring frame comprising a plurality of cross bars spaced apart, a connecting member at each end of said cross bars and securing the latter together, each of said members having a plurality of slots therein, a plurality of brace strips disposed between certain adjacent pairs of cross bars and each having an opening therein, a Z-shaped hanger slidingly mounted in the respective openings in said brace strips and in said end member openings to engage a bed frame under certain conditions to support said frame, an angularly disposed end or hook on each of said hangers, and'a supporting frame yieldingly mounted on said cross bars.

3. In a device of the character stated, a spring frame comprising a plurality of cross bars each having pairs of recesses therein, a plurality of helical springs mounted on each bar, a coil of each spring being seated in a pair of said recesses, a plurality of tie rods transversely disposed with respect to said cross bars, and each interlooped with a plurality of said springs, and a suitable frame mounted upon and attached to all of said helical springs.

4. In a device of the character stated, a spring frame comprising a plurality of cross bars arranged in parallel relation and disposed with the width of said bars vertical, upwardly turned ends on each cross bar formed by suitably bending said bars, a transversely disposed bar for each end of said frame and connecting said upwardly turned ends together, means to secure a plurality of helical springs to each cross bar; a plurality of brace strips, each arranged between certain adjacent cross bars and having an opening therein, a substantially Z- shaped hanger slidingly mounted in the opening in each brace strip, and adapted to engage a bed frame under certain conditions to support said frame, and a hook on the outer end of each hanger, each of said end bars being provided with guiding means for said hangers.

5. In a device of the character stated, a spring frame comprisin a plurality of cross bars spaced apart, an having upwardly turned end portions, a transverse bar connecting each set of upturned end portions and each having a plurality of slots therein, a lurality of brace members fixedly mounted adjacent each transverse bar, said members each having a slot therein and a Z- shaped hanger slidingly mounted in each brace member slot and also slidingly mounted in one of said transverse bar slots whereby said hangers may be extended beyond said transverse bars to engage a bed frame to support said spring frame;

. In testimony that I claim the foregoing as my invention, I have hereunto signed my name this 24th day of September, A. D.
